Beyond The Scientist’s coverage of COVID-19’s molecular underpinnings were many other stories highlighting the advances made in scientists’ understanding of the biology of cells.

Engineered antibodies trap and immobilize human sperm in the reproductive tract of female sheep, paving the way for possible use as a nonhormonal contraceptive in people.

A device that releases synthetic hormones slowly over time could one day provide a more practical alternative to daily birth control pills, say scientists.

Bardin’s work helped lead to the development of long-acting contraceptive devices for women.

A microneedle patch can subcutaneously deliver a contraceptive hormone to rats.

George Rosenkranz was part of a team in Mexico City that first synthesized norethindrone in 1951.

Such differences may help explain accidental pregnancies among women on the pill, researchers say.

A long-acting contraceptive patch with microscopic needles releases a drug slowly over time.

The gel, which men rub on their upper bodies daily, delivers synthetic progestin to block the testes from producing normal levels of sperm.

Sperm-binding, peptide–coated beads work as an implantable contraception device in mice and as a means of selecting human sperm for assisted reproduction techniques, researchers show. 

Carl Djerassi, who synthesized a hormone that was key to the creation of the birth control pill, has passed away at age 91.

Did 20th-century pharmaceutical and technological advances shape modern sexual behaviors?

In a proof-of-principle study, genetic deletion of two genes renders male mice infertile by preventing sperm transport through the vas deferens.

A new study suggests a possible link between the use of oral contraceptives and rising prostate cancer rates.
